4 Claims. 1

The principal object of the invention is the provision of a sprinkler which will provide means evenly distributing the sprays of water forced therefrom and distributed thereby.

A second object is the provision of a sprinkler device which is easy of assembly, and which requires no adjustment of the assembled parts.

Another object is the provision of an efiicient sprinkler device which is easy and economical of manufacture, and which may be sold at a nominal price.

Other objects and particularadvantages of the invention will suggest themselves in the course of the following description, and that which is new will be pointed out in the appended claims.

Like characters of reference designate like parts throughout the several views.

.In orderthat the advantages of the invention may be.-more fully understood and appreciated, I

will now take up a detailed description thereof in which the same willbe 'morefully set forth.

Referring now to the drawings in detail, the device is provided with a base member .1 which has a pair of forwardly projecting lugs formed thereon, with the same being turned upwardly to form runners for the base when the same is being pulled from one sprinkling position to another. The central portion of the base is slightly depressed and forms a seat 3 into which the sprinkler is rigidly secured through aperture 4.

The body 5 of the sprinkler is preferably formed of hexagon-shaped stock having a central bore 6 extending partially therethroug-h, with the outer end of the bore being enlarged and with threads 1 being formed therein and providing meansfor securing the sprinkler to the threaded end connection of a hose. A further relieved portion-B is formedbetween bore l5 and threads =1, and provides for the reception of 'a gasket washer member (not shown). The upper portion of body 5 is provided with an aperture 9. The lower portion .of the body has aperture 10 formed therethrough, with the aperture 1.!) being in alignment with aperture 9.

The device is provided with acentrally located upwardly projecting bearing imember H, with the same having a shoulder l2 formed below the upper portion thereof. The body portion'of the bearing member extends downwardly .from shoulder l2, with same forming ortion l3, and with portion 13' being separated from portion l3 by the channelled .recess 14. A plurality of water outlet apertures iii are formed through the wall of the recessed channel portion M. The bearing member is further provided witha downward extension it which is of lesser diameter than portion l3 and forming ashoulder ll, the purpose of which will be hereinafter more .fully set forth.

A revolving head member {8, having a centrally-located bore 19 formed therethrough, is adapted to fit against shoulder l2 of bearing member ll, and with the bore l9 fitting in revolving relation on portions 13 and 13'. :A plu- :rality of passages 20 are formed through the revolving head member 18, with the :outer ends of 3; with a washer member 22 being positioned on the extension 16 and located between the shoulder l1 and the upper surface of body 5, as shown more clearly in Figures 3 and 8.

The device is provided with a centrally located rivet 23 having a head 24 formed on the upper end thereof, with the rivet extending downwardly through the bearing member, the body member, and through aperture 4 formed in portion 3 of the base member, and with a lower head portion 25 being formed thereon. Members II, 22, 5, and the base member are tightly secured together by means of rivet 23, and with revolving head member l'8 being freely revolvable on the portions l3 and i3, and between shoulders l2 and H.

The members of the device shown in Figures 6, '7, 8, and 9, except the revolving head member 26, conduits 29, and jam nuts 3|, are like the same members shown in Figures 1 through 5 and Figures and 11.

Referring now especially to Figures 6, 7, 8, and 9, a modified form of revolving head member is shown, the same being designated by numerals 26. A bore 21 is formed vertically through the head 26 and through which the bearing member extends. Threaded apertures 28 are formed through the wall of the head member with the inner ends of the apertures registering and communicating with the channelled recess I i of the hub member. Conduits 29, having threads 36 formed on the inner ends thereof, are rigidly secured in the threaded apertures 28 by means of the jam nuts 3|. Each of the conduits 29 has a communicating passage 32 formed longitudinally thereof, and with a plurality of comparatively small apertures 33 being formed in the trailing side thereof. It will be further noted, by reference to Figure '7, that the outer end portions of conduits 29 are formed at a rearward angle with relation to the inner ends thereof, with the angularity thereof providing means, with the passage of water under pressure therethrough, to rotate the head member 26 on bearing 1! in the direction indicated by the arrow in Figure 7. Apertures 33 further provide means serving to rotate the head member by the passage of water therethrough.

It will also be obvious that water under pressure passing through the angularly-disposed passages of head member l8 causes the head to rotate on its bearing member II in the direction indicated by the arrow in Figure 4.

In the assembly of the device, as more clearly shown in Figure 5, the bearing member is placed on the rivet member with the upper end portion of the bearing member being in contacting relation with the under side of head 24. The revolving head is then placed on the bearing member with the upper end of the revolving head being set against the shoulder l2. Washer 22 is placed on extension 15 and set against shoulder ll, after which the body member is placed on extension 16 and against washer 22, and with the lower end of the rivet 23 extending through aperture ID of the body member. The lower end of rivet 23 is extended through aperture 4 of the base member, after which head is formed on the lower end of rivet 23, and tightly securing the base, the body, washer 22, and bearing II together. The revolving head member is free to revolve on the bearing member between shoulder l2 and washer 22.

Instead of head 25 being formed on the lower end of rivet 23, the lower end portion thereof may have threads formed thereon, and with a nut being tightened thereon to rigidly hold the members together.

It is to be understood that I am not to be limited to the exact forms and positions of the various members of the device, but that minor changes may be made therein, insofar as the changes thereto may fall within the scope of the appended claims.

Having now shown and described the invention. what I claim, is:
